Calculated power from the oxidation of biomolecules with oxygen at South Pacific Gyre (hole U1370, IODP Expedition 329)

<p>This sheet contains data on calculated power from the oxidation of biomolecules with oxygen at South Pacific Gyre (hole U1370, IODP Expedition 329).&nbsp;</p> <p>This project quantifies the role of microbial necromass and organic carbon as a power source to living microorganisms in marine sediments. The project utilizes a physiochemical model of marine sediment bioenergetics using data available in the literature and well-established modeling constructs. Data sources and model formulation are described in Bradley et al. 2018 (DOI: 10.1002/2017JG004186). For modelling South Pacific Gyre sediments, cell abundance and particulate organic carbon concentrations were determined for site U1370 (IODP Expedition 329) based on published analysis of extracted drill cores: D’Hondt et al. 2015 (DOI: 10.1038/ngeo2387); D’Hondt et al. 2011 (DOI: 10.2204/iodp.proc.329.2011). For modelling global cell abundance, we use the formulation described in Parkes et al. 2014 (DOI: 10.1016/j.margeo.2014.02.009).</p>本数据集工作表收录了南太平洋环流（South Pacific Gyre）U1370钻孔（国际大洋发现计划（International Ocean Discovery Program, IODP）329航次）中，生物分子经有氧氧化产生的计算功率相关数据。 本项目旨在量化海洋沉积物中微生物残体（microbial necromass）与有机碳作为活体微生物能量来源的作用。本研究借助海洋沉积物生物能学（marine sediment bioenergetics）的物理化学模型，结合已有文献数据与成熟的建模框架开展相关量化工作。数据来源与模型构建细节详见Bradley等人2018年发表的学术成果（DOI: 10.1002/2017JG004186）。针对南太平洋环流沉积物的建模分析，研究团队基于已公开的钻孔岩芯分析结果，确定了U1370钻孔（国际大洋发现计划329航次）的细胞丰度与颗粒有机碳（particulate organic carbon）浓度：相关数据源自D’Hondt等人2015年（DOI: 10.1038/ngeo2387）与D’Hondt等人2011年（DOI: 10.2204/iodp.proc.329.2011）的研究。针对全球细胞丰度的建模工作，本研究采用了Parkes等人2014年提出的建模方法（DOI: 10.1016/j.margeo.2014.02.009）。
